I am going to figure out why atoms attract, and win the nobel prize in physics. I am a winner. My mom told me so.
Gravity is what keeps the conservation of energy law valid. It's really simple if you think about it.
The universe is still expanding but it won't be forever. You see, as matter continues to drift apart from each other in the expanding universe, the only real force acting upon these mass is gravity. It doesn't matter if two objects as small as a tennis ball are 10^100 meters apart, there still exist a force of attraction between them. Suppose there are only two little tennis balls in the universe 10^000 meters away from each other not moving. Though it will take a long long long time, after 10^100000 years the two tennis ball will collide because of the gravitational force between them.
So as the mass in space are expanding outwards at a certain velocity, gravity is very very slowly but surely slowing down this expansion until at a certain point the expansion stops and the universe starts to suck itself back into the one giant mass of whatever that leads to the big bang. Like a swinging pedulum that swings back and forth forever in a self contained system, The Big Bang hurls everything outwards while gravity eventually brings it back. The energy bounces back and forth between the heat generated from massive clutter of mass prior to the big bang to gravity which eventually brings it all back.
Using the theory from above,
Maybe all gravity is nothing more than a rubber band that binds all matter.

Here's what I think. Gravity binds all mass in the universe together. It doesn't matter what mass you are in the universe, gravity binds you to all the other masses of the universe. Every single object is effected by the gravitational force of every other object. It's like everything is connected to every other thing by a cosmic rubber band.
Because of the above, I believe there HAS TO BE A GOD.
You see, before all matters were binded to each other by gravity, each matter of the universe can only set there motionless and not move.
Without gravity, nothing motivates these matteres to move. Objects not in motion stays motionless. Somebody came along and binded all these objects to each other and then give it a nudge to jump start this dynamic universe that we see today.

i'm not seeing the connection.....
anyways, nobody knows why gravity is the way it is.

What I meant was, someone had to have came along and set all this in motion.
Suppose when matter first appeared in this empty universe, it would just set there and do nothing.
Why should it move? I believe somebody must have came along, install this gravity system that binds all objects to each other and then gave the system a nudge to start it all.
I still don't get this logic. Gravity can't exist on it's own, it needs to be "set in motion" by something, i.e. God, but God doesn't have to be set in motion. Why can't gravity simply exist?
Why would the expansion of the universe reverse because of gravity? The further away two objects get, the less force pulling them together. If the universe was going to implode it would have done it already.
Yeah, that's what I think. It's like the chick or the egg question. Gravity gets it energy from the energy released in the Big Bang. The Big Bang happens because Gravity uses its energy to bring all matters together. How this energy is transfer from one to the other I don't know. So which happened first?
I prefer to think Gravity as an object. An awefully complicated object. It connects enything everything else. The whole universe as we know it is connected by this object we call gravity. When asking the question of where this universe came from, you have to answer
1. Where matter came from
2. How did all these matter get connected together by this object we call gravity
Maybe some people can argue that matter just came into being by itself. But this gravity that ties all matter together is a heck of a complicated system. I doubt something this complex happened on it's own which is the first reason why I believe there must be some super force out there that did it. 2nd reason, when matter first came into existance, what caused it all to oscillate(Big Bang)? I think most likely it's a super being that made the gravity system. That super being may or may not be the God that any of us worship, but I do believe this super being aka God exist.
It is true that the further away two objects get, the less the gravitational force is pulling them. But you also have to realize that there is NO FORCE driving these two object further from each other. Think of it this way. Suppose your driving your car at 80 miles per hour and you let go of the gas. Even though the force of the air pressing against the front windshield might be small, it will eventually stop your car with or without you stepping on the break.
The universe does not implode because of the Big Bang. As matter gather and build up heat etc etc..it eventually explodes and sends all matter hurling out into space. This is the expansion of the universe that we are at right now. Eventually, since energy cannot be created or destroyed, gravity brings it all back.
gravity = exchange of gravitons between matter. gravitons carry the gravitational force. Now they haven't found gravitons yet but they are sure they exist. Kinda like Gluons and stuff like that...
On a side note I really really hated high school physics.

HA !
Please try to explain to a blind person what light is
Better yet,explain it to me without using technical terms
